From: Leo Ruan Date: Fri, 8 Feb 2019 09:51:35 +0000 (+0100) Subject: splash: Use splashfile instead of location->name X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3d92f31762d8744e9b905b631dc267276adc50d4;p=project%2Fbcm63xx%2Fu-boot.git splash: Use splashfile instead of location->name The splash image could be loaded from different sources (e.g. sf, mmc) with different formats (e.g. raw, file-system). These sources are structured by a board dependent object 'splash_location'. To decide where is the splash image loaded, following environment variables are used to select the splash source and file: - 'splashsource' is used to select the splash source by setting its value to specified name of splash location. - 'splashfile' specify the name of splash image file But, when loads the splash image from FIT, the name of splash image within FIT is specified by splash location name. Due to the splash location name is already used for the splash source, its name may conflicts with the name of splash image. To solve the conflict, the environment variable 'splashfile' is used to specify the splash image in FIT, and keeps the splash location name for the splash source.
